Types of PRO Tips

ApplianceWatch has several types of PRO Tips to help you identify storage-related issues that occur between Data ONTAP LUNs and Hyper-V virtual machines. Some of the PRO Tips offer automatic remediation, enabling ApplianceWatch to fix the issue automatically if you choose.

The PRO Tips and their descriptions are as follows:

High LUN space utilization

This Tip is generated when space utilization on a LUN hosting one or more virtual machines crosses a specified threshold. The default threshold is 95 percent.

All nodes in a Hyper-V cluster must be monitored by Microsoft System Center Operations Manager. Information about the virtual cluster is collected from the active node. The LUN must be mapped to one or more drives on a host, but must not be mapped to any other host.

Hyper-V VM not replicated

This Tip is generated when SnapMirror is licensed but is not enabled on a volume that contains LUNs hosting virtual machines.

Hyper-V VM space utilization rate

This Tip is generated when ApplianceWatch determines that storage space might soon be consumed on the volume on which a LUN resides.

The default threshold rate is 2 percent, approximating to storage being consumed within 50 days. The default setting for displaying this Tip is once a day. A sampling rate of one day is used for the storage usage calculation.

You can configure both the threshold percentage rate and the frequency that the Tip is displayed.

There is no automatic remediation for this Tip.

Hyper-V protection is broken or long lag time

This Tip is generated when the volume in which a LUN resides has a broken SnapMirror relationship or a long lag time.

This Tip offers automatic remediation to perform a SnapMirror update.

LUN offline

This Tip is generated for a virtual machine if one or more storage system LUNs that serve that virtual machine is offline.

This Tip offers automatic remediation to bring the LUNs back online.

LUN-type igroup-type misconfiguration

This Tip is generated when the Hyper-V LUN type and the igroup type are mapped incorrectly between the storage system and the Hyper-V host for either Windows and non-Windows types.

If ApplianceWatch determines that the igroup type and LUN type are the incorrect Windows type, ApplianceWatch generates a warning Tip. If ApplianceWatch determines that the LUN type and igroup type are the incorrect non-Windows types, it generates a critical Tip. This PRO Tip is generated only when the installed version of Data ONTAP supports Hyper-V LUN and igroup types.

Thin provisioning LUN space reservation enabled

This Tip is generated when the LUN space reservation setting is enabled on LUNs hosting virtual machines. To provide thinly provisioned LUNs, LUN space reservation must be disabled.

This Tip offers automatic remediation to disable LUN space reservation.

Thin provisioning Snapshot auto delete disabled

This Tip is generated when automatic deletion of Snapshot copies is not set for volumes that contain LUNs hosting virtual machines.

This Tip offers automatic remediation to enable automatic Snapshot copy deletion on the volumes.

Thin provisioning volume autogrow for volumes hosting Hyper-V VMs

This Tip is generated when the volume autogrow option is not set for volumes that contain LUNs hosting virtual machines.

This Tip offers automatic remediation to enable volume autogrow.

Volume deduplication not enabled

This Tip is generated for a virtual machine when deduplication is licensed but not enabled on a storage controller that hosts storage system volumes serving two or more virtual machines.

This Tip offers automatic remediation to enable deduplication on the affected volumes.

Volume deduplication not licensed

This Tip is generated for a virtual machine when deduplication is not licensed on a storage controller that hosts storage system volumes serving two or more virtual machines.

This Tip does not provide automatic remediation, but it recommends installing a deduplication license in virtualized environments.

Volume offline

This Tip is generated for a virtual machine when one or more storage system volumes serving that virtual machine is offline.

This Tip offers automatic remediation to bring the volumes back online.

Volume space utilization exceeded threshold

This Tip is generated for a virtual machine when one or more storage system volumes that serve that virtual machine is full.

This Tip offers two configurable thresholds: a warning level that defaults to 95 percent, and a critical level that defaults to 99 percent.

This Tip offers automatic remediation to increase the volume size so that space utilization is reduced to 85 percent. The Tip also recommends that the virtual machine be paused by the SCVMM administrator to avoid running out of space.
